[edit] Description

Deblocking function based on blindPP and high/lowpass separating. This is of most use on HEAVILY compressed source material.

[edit] Requirements

[edit] Required Plugins

Latest version of the following plugins are recommended unless stated otherwise.

  • DGDecode - part of the DGMPGDec package


[edit] Syntax and Parameters

funkydeblock (clip c, int "quant", int "th", int "radius", bool "deblock", bool "depump")


clip   =
Input clip.


int  quant = 4
The quant parameter usually fed into blindPP. The default is 4 which is actually very conservative due to the fact it's only used on the highpassed clip, so even quant=31 gives a good picture.


int  th = 3
TemporalSoften threshold. Only active when depumping is on. Default 3. This parameter controls how sensitive to pumping the filter is. keep it low, unless you're seeing large jumps at I frames. Increase only as much as you have to, or dim moving objects will start vanishing.


int  radius = 4
The number of frames before and after currentframe used in TemporalSoften. Default 4. This is intended to smear GOP changes, so pumping doesn't show as much.


bool  deblock = true
Turn deblocking on/off (only depumping is used). Default true.


bool  depump = true
Turn depumping on/off (only deblocking is used). Default true.


[edit] Examples

funkydeblock with default settings: 

MPEG2Source("Blocky.dv2")
funkydeblock (quant=4, th=3, radius=4, deblock=true, depump=true)


[edit] Script

function gauss (clip c, int "radius") {

radius=default(radius,1)

radius=radius*4
c.bilinearresize(4*(c.width/radius),4*(c.height/radius)).bicubicresize(c.width,c.height,1,0)

}

function funkydeblock (clip c, int "quant", int "th", int "radius", bool "deblock", bool "depump"){

quant=default(quant,4)
th=default(th,3)
radius=default(radius,4)
deblock=default(deblock,true)
depump=default(depump,true)

blurd = c.gauss(4)

highpass=subtract(blurd,c)
deblocked=(deblock==true) ? highpass.blindpp(quant=floor(quant),cpu=4) : highpass

nopump=subtract(blurd,deblocked)
pump=subtract(blurd.temporalsoften(radius,th,th,2*th,2),deblocked)

(depump==true) ? pump : nopump

}
